Regarding the principle of isolation insulation, sleeping mats, sleeping bags and warm clothing is the same: Between our bodies and the cold external environment, they are firmly catching some air and make them do not flow, our bodies will slowly heating the air, this way, they become our isolation barrier. Sleeping mats isolation effect to a large extent depends on how much air t can retain and freedom of the air.
The following is a selection of camping sleeping pads several main factors:
Degree of comfort
Weight and volume
If you're only camping for those days of good weather, comfort is more important than the isolation effect.

Closed-cell foam material mat: Cheap, durable, and thermal isolation effect is excellent. Moreover, this mat does not absorb moisture and water. But they relatively are more rigid, and its cushioning effect is not better than the open cell foam.
Inflatable Mattress: as comfortable as an open-cell foam material, but isolation insulation effect is better, the quantity of intake air can be adjusted and the package can be very compact. But it is more expensive and bulky than other types of sleeping pads. Moreover, it will be punctured or split.
